FLUSHING ATTACHMENT FOR WATER-CLOSETS.

SPECIFICATION forming part of Letters Patent No. 569,559, dated October '13, 1896.

Application filed April 13, 1892. Serial No. 428,975. (No model.)

To all whom it may concern:

Be it known that I, PATRICK J. MADDEN, of Rochester, in the county of Monroe and State of New York, have invented a certain new and useful Improvement in Flushing Attachments for ater-Closets; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the drawings accompanying this application.

The present invention relates to that class of flushing attachments in which the valve for controlling the admission of water to the bowl consists of a disk and is seated by the downward movement ofthe hinged seat, an example of which is shown in Patent No. 374,310, which was granted to me on the 6th day of December, 1887.

The object of the invention is to provide an adjustable connection between the said valve and hinged seat, to the end that the parts may be so adjusted that when the seat shall have come to a firm bearing upon the top of the bowl the valve will be seated firmly, but not with such undue pressure as to strain the seat-hinges or other parts. Where the water is first introduced under pressure to an air-tight flushing-tank and is afterward discharged into the bowl by the compressed air, it is desirable to make relatively adjustable the valve and valve-seat which control the admission of the water to the bowl, and when they are so adjustable it is necessary that the connection between said valve and the hinged seat be also adjustable, otherwise the valve may be seated with a pressure which is not sufficient to prevent leakage, or else it may be seated with an excessive pressure, and thereby injure its face and strain the seathinges and other parts.

The invention consists in the features of novelty that are particularly pointed out in the claims hereinafter.

In the accompanying drawings, which are made a part of this specification, Figure 1 is a sectional elevation of a water-closet embodying the invention. Fig. 2 is a section of a portion of the bowl on the line 00 cc, showing the waterways therein. Fig. 3 is an enlarged sectional elevation of the valve mechanism and accessories, the section being taken in a vertical plane passing through the axes of the several branches of the water-supply pipe. Fig. 4 is an enlarged sectional elevation showing in detail the adjustable connections between the hinged seat and the valve-stem.

A represents the bowl; B, the seat hinged thereto; 0, the flushing-tank; D, the watersupply pipe; E, a pipe communicating with the tank, and F a valve-casing having two branches, with each of which one of said pipes communicates, and a third branch communicatin g with the bowl through a pipe F, which forms, in fact, a part of the valve-casing. Directly in line with this latter branch and separated therefrom by a perforated diaphragm, which is provided with a valve-seat la, the casing is provided with a chamber I, closed by a screw-cap Z, and into this chamber opens that branch of the casing with which the supply pipe D communicates. lVithin said chamber is located a valve 2', provided with a stem H, that projects from it in both directions, one portion of said stem extending through the perforated diaphragm aforesaid, while the other portion extends into a socket Z, formed for it on the cap Z, and is surrounded by a coiled spring I), which exerts its force to hold the valve normally. seated.

Located within that branch of the casing that leads to the bowl is an adjustable valveseat 01 and a disk-valve 0, adapted to close upon said seat and thereby cut off the flow of water to the bowl. This valve is provided with a stem G, which projects from it in both directions, one portion of said stem being surrounded by a spiral spring a, by which the valve is held normally unseated, while the other portion extends through an opening in the otherwise closed end of the pipe F and projects into the bowl, where it is provided with an antifriction-roller f.

The two valve-stems G and H are located directly in line with each other, and one is provided in its extremity with a concavity for receiving and centering the other when they are brought together by the inthrust of the stem G, as hereinafter described. Normally, however, the spring a holds the parts in such positions that the valve 0 is unseated and the valve-stems separated, and it is not until the valve 0 has nearly completed its movement toward its seat that the stem G comes in contact with the stem II and unseats the valve 2 The spring a is of such strength that it holds the seat elevated, acting through the medium of the stem G and an arm g, carried by and projecting downward from the seat I5. This arm is connected to the seat mediately, (through a pivot m, a pair of perforated lugs through which said pivot passes, and a baseplate from which said lugs project, said baseplate being secured to the seat immediately,) and the arm is provided with a lateral extension 1), through which is tapped a set-screw 'n, which engages the base-plate aforesaid. By this means the arm g may be adjusted (within the limits of the capacity of the set-screw) to any desired angle with relation to the plane of the seat, so that the seat will be held elevated at just such height that its movement in descending to a bearing upon the top of the bowl will give just enough movement to the valve 0 to seat it. In this way the connections between the valve 0 and the hinged seat may be so adjusted as to attain the objects hereinbefore pointed out.

The term disk-valve as used in this specification is intended to comprehend all of those valves whose working faces are not parallel with the direction of movement, and which in operating move toward and from their seats.

What I claim as new, and desire to secure by Letters Patent, is

1. In a water-closet, the combination with a bowl, and a water-supply pipe having a branch communicating therewith, of a valve and valve-seat located in said branch and being relatively adjustable for the purpose of regulating the flow of water past them, a hinged seat, and connections between said hinged seat and valve, whereby movement of the seat is transmitted to the valve, said connections being adjustable substantially as and for the purpose set forth.

2. In a water-closet, the combination with a bowl, an air-tight flushing-tank into which water is forced under pressure, a pipe for conveying water from the tank to the bowl, and a relatively-adjustable valve and valveseat arranged in said pipe, of a hinged seat and connections between said hinged seat and valve, said connectionsbeing adj ustable, substantially as set forth.

8. In a water-closet, the combination with a bowl, a water-supply pipe communicating therewith, a disk-valve for controlling the flow of water through said pipe, anda hinged seat, of connections between the hinged seat and valve, said connections including the pivoted arm g having a lateral extension 1) and a set-screw engaging said extension for the purpose of adjusting it, substantially as set forth.

at. In a water-closet, the combination with a tank, a bowl, and a valve-casing having a branch commu nioatingwith the water-supply pipe, a second branch communicating with the tank, a third horizontal branch communicating with the bowl, a perforated diaphragm located opposite this third branch and resulting in a chamber with which the branch first aforesaid communicates, and a screw-cap closing said chamber, of a valve located in said chamber, a spring holding said valve normally seated, a valve-seat and valve located in the third branch of the casing, a spring holding said valve normally unseated, a horizontal stem carrying said valve and projecting from the valve-casing, a hinged seat, a projection carried by the hinged seat and projecting downward therefrom and adapted to engage said stem, and means for transmitting movement from the valve last aforesaid to the valve first aforesaid,substantially as set forth.

In witness whereof I have hereunto signed my name in the presence of two subscribing witnesses.

PATRICK J. MADDEN.
